Dear Stable,
Commit 844cf763fba6 ("tipc: make macro tipc_wait_for_cond() smp safe") replaced finish_wait() with remove_wait_queue() but still used prepare_to_wait(). This causes unnecessary conditional checking before adding to wait queue in prepare_to_wait().
This commit replaces prepare_to_wait() with add_wait_queue() as the pair function with remove_wait_queue().

Could we have this ol' classic backported to v4.19 and v4.14 please?
